Lookalikes to avoid
These look similar but are different characters:
| Character | Unicode name | Code point | What it is for |
|---|---|---|---|
| ℃ | DEGREE CELSIUS | U+2103 | DEGREE CELSIUS, a single character kept for compatibility with older character sets. Unicode advises writing ° followed by C instead. |
| ℉ | DEGREE FAHRENHEIT | U+2109 | DEGREE FAHRENHEIT, also a compatibility character: its standard decomposition is ° + F. |
| K | KELVIN SIGN | U+212A | KELVIN SIGN (U+212A). Unicode recommends the ordinary capital K (U+004B) for the kelvin. |
| º | MASCULINE ORDINAL INDICATOR | U+00BA | MASCULINE ORDINAL INDICATOR, a letter used in Spanish and Portuguese ordinals, not a degree sign. |
How to write a temperature
The International System of Units puts the number first and a space before the unit: 30.2 °C, not 30.2°C or 30.2° C. The degree sign and the C stay together.
Celsius to Fahrenheit
°F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9. Some values, worked out with that formula:
- −40 °C = −40 °F
- −10 °C = 14 °F
- 0 °C = 32 °F
- 10 °C = 50 °F
- 20 °C = 68 °F
- 25 °C = 77 °F
- 30 °C = 86 °F
- 37 °C = 98.6 °F
- 40 °C = 104 °F
- 100 °C = 212 °F
The kelvin has no degree sign
Since the 13th General Conference on Weights and Measures (1967–68), the unit is the kelvin, symbol K, and never “degree Kelvin” or °K: 300 K.
Frequently asked questions
How do I type °C on Windows?
Hold Alt, type 0176 on the numeric keypad, release Alt, then type a capital C.
Should I use ℃ or °C?
°C. ℃ is a compatibility character whose standard decomposition is ° + C, and Unicode advises the two-character form.
How do you convert Celsius to Fahrenheit?
Multiply by 9/5 and add 32: 20 °C × 9/5 + 32 = 68 °F.
Is there a space between the number and °C?
Yes, under SI rules: 25 °C. Angles are the exception and take no space: 30°.
